I only reserve full price spending every once in a while for games I'm particualrly excited for, which doesn't happen often. These include GTA V, Skyrim, and The Witcher 3. Most games I can wait for a price I feel is reasonable for me (around £20 usually)
Hmm, your 2gb vram may only really allow middle graphics at best I'd say. I'm gonna be playing on a 780ti (3gb) and I'm not expecting to be able to max this thing 60fps. Honestly though, I'd say you'll still get a fairly fine looking game with those specs, just don't expect to reach the upper tiers of graphic settings.
There's a lot of good indie stuff if you didn't play it on xbox already. Dust: An Elysian Tail, Dragon age 1 (haven't played the others) if even just for the isometric camera; it really does make that much of a difference. More recently perhaps Ori, although I haven't played that myself. Oh and Gang Beasts if you've got friends! (hence why it's not in my library haha)
Gta V when it comes out. I'm going to get it solely for the inevitable 'GTA IV Driving Physics mod'.
